MOVABLE W'ALL.

Application filed February 19, 1925.

This invention relates to improvements in movable wall structures.

It is an object of this' invention to provide an improved movable wall structure, which is adapted to be used in storage buildings or warehouses. n

l-leretofore storage buildings have been constructed with a plurality ot rooms or cells built-in in the building. Frequently a person wishing to store his goods does not have a suflicient quantity to completely fill one of the rooms in the storage building. By use of the improved movable wall structure, the goods may be stored adjacent one ot' the building walls oil the storage building, and when they have been properly ar.- ranged, a movable wall may be moved up to the stored goods, so as to dene separate room containing them. The next person, who wishes to store his property, places his goods next to the movable wall section, and a second movable wall cooperates with the first movable wall to enclose the property of the second person. ln this manner the space in a storage building may be used to the best advantage.

lith the foregoing and other objects in view which will be made manifest in the following detailed description and pointed out in the appended claims, reference is had to the accompanying drawings for an illustrative embodiment ont the invention, wherein:

Figure 1 is side elevation of two sections of which the improved movable wall may be formed;

Fig. 2 is a vertical section taken substantially on the line 2 2 of Fig. 1;

Fig. 3 is a horizontal section take on the line 3 3 of Fig. 1;

F ig. et is a perspective view illustrating one of the jack screws and brackets used upon the movable wall; and

F ig. 5 is a perspective view showing th connecting means for connecting two adjacent sections of the movable wall together.

Referring to the accompanying drawings wherein similar reference characters designate similar parts throughout, the floor oi the -building is designated at 10 and the ceiling at 11. The movable wall is shown for purposes or illustration as composed of two sections 12 and 13. These sections may be or' any suitable. construction and are preferably hre-proof. As an example of one of the sections, they are shown as consisting of uprights 14 and 15 connected by top and Serial No. 10,322'.

bottom cross bars 1.6 and 17 and an intermediate cross bar 18. Sheet metal 19 is secured over the frame formed by the uprights 14% and 15 and the cross bars 16,- 17 and 18. Adjacent the upper corne-rs of each section, there are placed brackets, generally designated at 20, having a central portion A21 adapted to be secured to the section as by bolts 22 which are provided with nuts 23. The upper end of the central portion 21 is bent outwardly, as at 2li, and has an aperture therethrough, which is threaded. The lower end o't the central portion 21 is bent outwardly, as at 25, and has an aperture 26 therethrough, A jacl screw `27, which has its upper end threaded finto the `aperture in the outwardly extending portion 2li, has its lower end extend-ing through the aperture 26 and is provided with a head 28,l to which may be applied ya wrench. engaging head 3U is swivelcd upon the upper1 `end of the jack screw 27.

rl`he connecting means: for connecting two sections together consists of two angular lugs 31 and 32, which are pivotally secured to their respective sections as by bolts 33 and 34. The portions of the lugs 31 and 32, which extend outwardly from the sections, have apertures therethrough adapted to receive. a bolt 35 upon which is adapted to be threaded a nut 86.

The operation of the device is as follows:

llhen it is desired to iorm a wall at any location between the floor 10 and the ceiling 11, the sections are moved into position and by turning the jack screw 27 by applying a wrench to the head 28, the swiveled engaging head 30 will be forced upwardly so as to engage upon the ceiling 11, thus forming a tight or rictional engagement between the wall sections and the floor and the ceiling. The sections, if desired, may be turned upside down, so that the jack screws 27, instead of engaging upon the ceiling, might engage upon the floor, but the construction illustrated is preferred, for in this manner the jack screws do not have to support the weight of the sections as well as form a tight lit between the floor and ceiling. Vhen the sections are properly arranged, the bolt 35 is passed through the lugs 31 and 32, and the nut 36 is then screwed uponit. If for any reason theloor 10 should 'be slightly uneven, one of the lugs might become positioned slightly above the other. As the lugs are pivotally mounted to their respective sections, they may assume any position necessary tpl permit the bolt to be passed through t em.

When it is desired to remove the wall, itV

is merely necessary to unscrew the jack screws 27 so as to disengage the engaging head 30 from the ceiling, and the wall sections can be then be readily removed. As clearly shown upon Fig. 2, the jack screw 27 is preferably upwardly inclined toward its section. I have found that if the jack screw is vertical, or, in other words, parallel to its section, when it is tightened, it will tend to buckle the section, but inclining the jack screw, this buckling effect is greatly eliminated.

It will be understood that various changes in the detail of construction may be made without departing from the spirit or scope of the invention as kdelined by the appended claims.

I claim:

1.*In a movable wall, having extension means adapted to increase and decrease the height of the wall so as to cause the wall to be frictionally engaged between the iioor and the ceiling, said means including a bracket, an adjustable clamping means passing through said bracket and making an acute angle with the plane of said wall.

2. In a movable wall, having extension means adapted to increase and decrease the height of the wall so as to cause the wall to 'be frictionally engaged between the ioor and the ceiling, said means including a U- shaped bracket associated with said wall having guiding openings in each end, one ot said openings being farther from said. wall than the other, and a screw adjusting device passing through said openings.

3. In a movable wall, having extension means adapted to increase and decrease the height of the wall so as to cause the wall to be frictionally engaged between the floor and the ceiling, said means including a bracket associated with said wall having guiding openings in each end, a screw adjusting device passing through said openings, and having a swiveled engaging head thereon.

et. A movable wall extension bracket having bent ends, each of said ends having a guiding opening therein, and adjustable clamping means passing through said guiding openings and making an acute angle with said bracket.

In testimony whereof I have signed my name to this specification.
